FWIW, it turns out kernel 2.6.32-6-pve still isn't working for me 
either.  I determined that the panic happens while iptables is trying to 
reject a packet.  It only happens sometimes, but when it does, the panic 
is immediate.  When it sends the corresponding ICMP message, apparently 
some of the ICMP packet is corrupted even before it leaves the kernel 
and the panic occurs promptly thereafter.  The trace (including the 
iptables log entry) looks like this:

DROP icmp IN= OUT=vmbr1 SRC= DST= LEN=197 TOS=0x00 
PREC=0xC0 TTL=64 ID=54238 PROTO=ICMP TYPE=192 CODE=228
Kernel panic - not syncing: stack-protector: Kernel stack is corrupted

Notice ICMP packet: type=192, code=228.  I assume that's corruption. 
It's different every time: I've also seen type=110, code=46.

I've switched to 2.6.18, which is working fine, but I am willing to test 
more versions of 2.6.32 if you would like me to.  It's the least I can 
do for you guys.
